## VikingUAS Multicopter (VTOL)- Aircraft Safety Check list

Before Your First Flight.... Balance • Is the longitudinal center of gravity (fore and aft) within the range shown on the plans? • Is the model balanced laterally (side to side)? Control Surfaces • Are all control surfaces securely attached? (i.e., Props , booms, landing gear). Pull on each one to test. • Are the sensor secured to the model? Control Linkages • Have all the linkages been checked to be sure they are se cure? Engine / Motor Security and Operation • Are all engine mount screws tight, including mount to motor mount • Are the propeller nut and/or spinner tight? • Does the throttle work without binding? • Does the throttle trim tab shut down the engine? • Has the propeller been balanced and checked for damage? • Are propeller tips painted a contrasting color? (whilst not essential it makes the propeller much easier to see) • Has the engine been thoroughly test run? (engine idl e and throttle up properly) Radio Equipment • Are the receiver and battery securely mounted and padd ed with foam to protect from vibration and shock? • Are all electrical connectors are secure? • Is the receiver's antenna fully extended and in good condition? • Are the batteries charged and in good condition (che ck under load with a volt meter if unsure)? • Are all servo/brushless motors securely fastened to the rails or trays? • Are servo arms/ brushless motors firmly attached with scre w in place? • Are all push rods firmly secure in servo arms (again keep ers or fuel tubing should be fitted)?  Are the control throws in the correct direction with proper amount of deflection (as per pl an)? • Has a full range check been performed? (see below) General • Is the covering tight with no visible signs of damage? • Are all retaining bolts in place and secure? • Are any hatches, cowls and canopies secure? • Are all components structurally sound? • Is your name and contact details marked on the model som ewhere easily visible? (in case it's lost).Range Checking the radio • Verify Ground Station and Radio Frequency is linked wi th aircraft. • Turn on transmitter check the correct model is selected (i f applicable) and then turn on the receiver. Important : make sure the transmitter aerial is down fully. • Ask someone to help and walk away from the model until signs of loss of control are apparent. • If electric powered ensure that the range is not worse with the motor running. Before EVERY flight: • Verify your frequency is available and mark it as your s if necessary. • Check the receiver battery pack to ensure enough charge f or the flight intended. • Check for damage and the control throw direction of all surfaces. • Turn on the transmitter and check the correct model is selected (if applicable). • If the model has a receiver battery then, switch on th e receiver. • Ensure the throttle is in the correct position and conn ect the motor battery. Flight Operations • Flight operations are to be conducted outside 5 mil es of any airport. If operations are to be conducted follow FAA instructions instructing ATC contact and time of operation requi rements in advance of flight operation. • If operating near a local airfield contact Airport Manager of Operations in area. This is to insure all GA pilot s are notified of the UAV/UAS operations in area. WARNING: The motor must now be considered live as the motor coul d start at any time without warning (possibly due to interfer ence or faulty controller). • Arm the controller if necessary and briefly check the moto r functions correctly. • Take the model out to the strip and warn people you are about to take off. • As soon as you land disconnect the motor battery and swit ch off the receiver if necessary. • Switch off the transmitter and release the frequency for others to use.
